Compressive Strength of Concrete -Cube Test, Procedure,

For cube test two types of specimens either cubes of 15cm X 15cm X 15cm or 10cm X 10cm x 10cm depending upon the size of aggregate are used. For most of the works cubical molds of size 15cm x 15cm x 15cm are commonly used.A Simple Guide to Concrete Cube Testing - QEM Solutions,The cubes should be covered with a damp cloth and a plastic sheet and stored in dry environment at a temperature range of 20 ± 5 degrees. The concrete cubes are removed from the moulds a minimum 16 hours later to a maximum 72 hours, usually this done after 24 hours. Make sure the cube ID is transferred to the cube before placing into a curing,Compressive Strength Test Of Concrete - Detailed Guide,The specimen should be weighed before the test. The specimen should be placed between the plate with proper alignment. Now, apply the load (kilonewton) gradually to the specimen. The specimen will break at maximum load (1 Division = 5 KN), which is noted down as the crushing value of the cube.
